摘要： A method of forming a Chemically Vapour Deposited polymeric conformal coating on a surface of a part (23). The method comprises placing the part (23) and a deposition regulator (28) in a deposition chamber (22); dispersing a gas into the chamber (22) from which the polymeric coating is deposited on the surface. The deposition regulator (28) is configured to control a localised flow of the gas in the deposition chamber (22) to promote a more uniform layer thickness of the polymeric coating on the surface.

摘要： An optical measurement instrument includes optical coherence tomography (OCT) interferometer and a pupil retro illumination system which directs laser light onto the retina of an eye via the sample arm of the OCT interferometer. The laser light passes through an intraocular lens (IOL) implanted into the eye, and an iris camera captures an image of the eye from a portion of the light returned from the retina of the eye, the returned light also passing through the IOL. One or more fiducials of the IOL are detected from the captured image, and an angular orientation of the eye is ascertained from the one or more detected fiducials.

摘要： At a first timing when a tightening machine temporarily tightens a bolt, a distance sensor acquires a first distance image. A distance sensor controller measures a first recess amount of the head of the bolt at the first timing by the first distance image. A manipulator controller is configured to change a relative posture of an image sensor relative to the head of the bolt in accordance with a rotation angle by which the bolt is rotated from the first timing to a second timing. The distance sensor acquires a second distance image at the second timing, and the distance sensor controller measures a second recess amount of the head of the bolt at the second timing by the second distance image, so as to measure an axial tension of the bolt by use of a difference between the first recess amount and the second recess amount.

摘要： Various systems and methods for sequential angle illumination to achieve ultra-high resolution optical coherence tomography (OCT) images. One example OCT system includes a light source, a beam divider, sample arm optics, a detector, and a processor. The light source generates a light beam to illuminate the sample. The beam divider separates the light beam into reference and sample arms. The sample arm optics sequentially illuminates a location in the sample with the light beam from different angles. The detector receives light returned from the reference arm and the sample illuminated at each angle and generates signals. The processor combines the signals to generate an image, which has a transverse resolution that is higher than the transverse resolution achieved from the signal generated from a single angle.

摘要： Improved optical coherence tomography (OCT) imaging systems are generally described. In an example, an OCT imaging system includes a tunable laser source, an interferometer, a splitter, and a detector. The tunable laser source is configured to provide a wavelength-scanned beam. The interferometer is configured to split the wavelength-scanned beam into a reference beam and an object beam. The splitter is configured to split the object beam into a first path corresponding to an anterior chamber imaging component and a second path corresponding to a retinal imaging component. The detector is configured to detect a signal caused by interference between the reference beam and at least a portion of the object beam reflected from the eye.

摘要： Presented is a speckle interferometer for measuring displacement of an optically irregular surface of a specimen having, a laser for producing a beam of coherent radiation, an adjustable polarizing beam splitter for dividing the radiation into a first portion of the radiation and into a second portion of the radiation. The reflected radiation is then passed through a pair of collimating lenses onto the optically rough surface of the specimen. The reflection off of the specimen is captured by an imaging system that processes the reflection to measure strains on the surface.

摘要： Multichannel optical coherence systems and methods involving optical coherence tomography (OCT) subsystems are operably and respectively connected to optical fibers of a multichannel optical probe, such that each optical fiber forms at least a distal portion of a sample beam path of a respective OCT subsystem. The optical fibers are in optical communication with distal optical elements such that external beam paths associated therewith are directed towards a common spatial region external to the housing. Image processing computer hardware is employed to process OCT signals obtained from the plurality of OCT subsystems to generate an OCT image dataset comprising a plurality of OCT A-scans and process the OCT image dataset to generate volumetric image data based on known positions and orientations of the external beam paths associated with the OCT subsystems.

摘要： Inspecting a multilayer sample. In one example embodiment, a method may include receiving, at a beam splitter, light and splitting the light into first and second portions; combining, at the beam splitter, the first portion of the light after being reflected from a multilayer sample and the second portion of the light after being reflected from a reflector; receiving, at a computer-controlled system for analyzing Fabry-Perot fringes, the combined light and spectrally analyzing the combined light to determine a value of a total power impinging a slit of the system for analyzing Fabry-Perot fringes; determining an optical path difference (OPD); recording an interferogram that plots the value versus the OPD for the OPD; performing the previous acts of the method one or more additional times with a different OPD; and using the interferogram for each of the different OPDs to determine the thicknesses and order of the layers of the multilayer sample.
